Keep getting asked for Login

We are at version, and can login with no issues to the dashboard. But then every page that we try to visit , we are then asked to login again (sometimes getting stuck in a loop). Any ideas?

Do you by chance have some kind of external caching turned on? Varnish or cloudflare? Both of those cause similar issues.

Thanks for the response. I think that It may have cloudflare - but will need to check when I can get access to the cpanel. Hopefully we should be able to turn it off fingers x'd. Thanks again

Hi there, thanks for your help, cloudfare was activated. It has now been killed and everything is fine again. Thanks again
